Promotion Is Applying Twice

I have a product in my cart. I add a promotion, say (GET5OFF). After it is applied it states:

Coupon “GET5OFF” X

Applied promotions

Get $5 Off

Get $5 Off

And the promotion is applied twice, thus giving $10 off. This seems to happen regardless of the number of products I have in the cart.

Both applied promotions are tied to a single entry because you can remove both by clicking the “X” to the right of ‘Coupon “GET5OFF”’.

Any insight into why this is happening?
